Abstract: Cloud computing is a highly scalable and cost-effective infrastructure for running Web applications. E-learning or e-Learning is one of such Web application has increasingly gained popularity in the recent years, as a comprehensive medium of global education system/training

systems. The development of e-Learning Application within the cloud computing environment enables users to access diverse software

applications, share data, collaborate more easily, and keep their data safely in the infrastructure. However, the growing demand of Cloud

infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of Cloud providers, but also leads to high carbon emissions which is not

environmentally friendly. Hence, energy-efficient solutions are required to minimize the impact of Cloud-Oriented E-Learning on the

environment. E-learning methods have drastically changed the educational environment and also reduced the use of papers and ultimately

reduce the production of carbon footprint. E-learning methodology is an example of Green computing. Thus, in this paper, it is proposed a Cloud-Oriented Green Computing Architecture for eLearning Applications (COGALA). The e-Learning Applications using COGALA can

lower expenses, reduce energy consumption, and help organizations with limited IT resources to deploy and maintain needed software in a

timely manner. This paper also discussed the implication of this solution for future research directions to enable Cloud-Oriented Green
